Unsold Slaves Returned as Heroes

38. I’m the only one who needs to listen to this lecture!

“The 5th level magic is so fast….”

“Wasn’t it the utilization professor?”

“Are you a slave trader?”

“Great!”

Students exclaimed.

Behind my back, five main magic circles are floating in the air.

Um… What’s next?

I’ve tried connecting two.

Then Tia flicked her finger. Auxiliary magic circles were engraved between my main magic circles, and then the casting continued as it rotated.

You have good skills.

Paaat―

A reduced sky is summoned from the ceiling of the classroom. It is a planetarium where small stars made of mana shine.

“Wow, that’s pretty.”

“It’s an celestial projection! Oh my god.”

“I summoned the real universe to the classroom!”

Leaving behind the admiration of the students, he manipulated the stars and made them into a map of the continent.

It is displayed in an easy-to-understand manner by spreading red stars and blue comets.

“Blue is a dungeon I have conquered, and red is an intermediate or higher level dungeon location that has appeared in the past 10 years.”

“Six Intermediate or Higher Attacks….”

“You mean at least the 10th floor?”

“Looking at the 5th tier magic, it must be real….”

I was lectured.

“Since you have no experience in dungeon raiding, I will emphasize it a little more.”

My voice echoes off the classroom walls.

“You can’t always predict what will happen in a dungeon, and a small mistake can lead to death. Even on the first floor, which we have attacked dozens of times, the dungeon is where B-class adventurers die.”

The stars on the ceiling draw the shape of the dungeon.

“The average survival rate on the first floor of the dungeon is 98%. Do you understand? There are about 50 people in this classroom right now.”

I clenched my fist. In an instant, the sky cracked and shattered, and the astronomical projection ended. The students were astonished.

“It means that when everyone in this classroom comes out just by stepping on the first floor of the dungeon, one person is missing.”

There was a quiet tension. I relaxed the atmosphere with a light smile.

“Of course, as long as I am there, that won’t happen even if I clear the 5th floor. Trustworthy talented people will be with you, so let’s all bloom. Hey, do you like candy?”

“Yes? Ah yes….”

I handed the candy to the frightened student sitting in the front row.

“Ah, no matter how much you die on the first floor. We’re not new adventurers, are we students of Caseus?”

It was the third year of the Wind Hall. It was a student who raised his hand saying he had experience in raiding dungeons earlier. He seemed to be confident in his skills.

“Hey, can you beat the goblins?”

“Isn’t that obvious? It was nothing. All three were killed in an instant.”

“A weak monster. He’s small, has no strength, and can’t use magic. Only use crude weapons. As for animals, yes. It’s no different from a dove. Do you agree?”

“It is as you said!”

“Even those pigeons kill people when they get together.”

“Yes? What do you say?”

The wind coffin student raised the corner of his mouth as if he was dumbfounded. I signaled by tapping the table.

Jumping! Charleureureu-!!

The classroom windows opened all at once, and hundreds of pigeons flew into the classroom.

“aaah, what a surprise!”

“Where did you come from!”

Out of the window, I could see Sersi pushing the pigeons she had prepared so hard.

In an instant, the classroom was filled with flying pigeons. It’s to the point where I can’t see the front. Students waved their arms around as the feathers fluttered here and there.

The raid of pigeons did not last long. Sersi used her magic to bring them back through the window.

I canceled the small animal extermination magic I had lightly applied. Not even a speck of dirt was left on my body.

“What is this….”

“That’s a group of goblins. This is a situation that we often encounter due to the bottleneck at the monster spawning area on the 1st floor.”

Most of the students were lost.

“You are injured by the number of feathers on your uniform. Where did you survive?”

The Wind Crown student, who had been full of confidence until a while ago, looked at me unfairly while still covered in pigeon feathers.

“Ha, but that was just a surprise….”

“Did you see the monsters warn before attacking?”

The wind coffin student fell silent.

“Even in the situation just now, there are students who perfectly defended themselves. Take a look around.”

Students look around the classroom.

Luca, Tia, and Yuri sat side by side in a calm and clean state as if nothing had happened.

Aside from that, about 10 of the students of the Land Hall, including Xuehua and the Imperial Princess, defended themselves. There are a few students in the other dorms that could be used.

I used short-term cleaning artifacts that I had prepared ahead of time. Students and classrooms are clean again.

From noble mtl dot com

“Proud Keisus Academy guys.”

“If you complete my lecture, I promise to increase your survival rate in the dungeon a hundredfold.”

Many students seemed to have come to their senses, their eyes wide open.

Of course, not everyone agreed.

“This is nonsense! Isn’t the Dungeon Studies lecture a theory class? Why doves suddenly appear! How many times do you have to go to a dungeon in your life?”

An aristocratic student whose hair was tousled by pigeons complained.

“Hey, did you not hear the lecture at the beginning? The professor made it clear that interrupting the lecture is prohibited.”

A voice like a sharp knife of ice echoed through the lecture hall. It was glass.

“Do you think dungeon studies can only be used in dungeons? Do you think you’ll never run into a monster in your life when you go outside?”

Tia also glared at the aristocratic student.

“Get out.”

Luca said a short word.

“Oh, no. What’s so scary….”

The female student next to the noble student stopped him by grabbing his arm.

The name was . It belonged to the Water Coffin.

“I have a question for you, Professor.”

“Let’s try.”

“Could you explain this dungeon?”

Shion pulled out one of her crystal spheres. She was a projection device. As she breathed her mana into it, a map and the image of a dungeon appeared in the air like a hologram.

“It’s a dungeon that appeared in the southwestern part of the kingdom. What are the measurement results?”

“The 5th floor, a low level dungeon.”

“But, judging from the fact that you’re asking, there must have been something special.”

“Yes. The five D-rank parties and the C-rank three parties who have already entered the advance party have lost contact. So, I urgently dispatched an A-rank party and attacked the 5th floor in an instant….”

“The missing adventurers couldn’t be found, and the dungeons probably weren’t subjugated.”

“… How?”

Shion gasped in surprise.

“Then it’s quiz time here. Why should I not neglect the dungeon and subdue it quickly? If you answer first, I will reward you.”

A few raised their hands. Of course, Luca, Tia, and Yuri also responded right away, but decided to give other students a chance.

“Mark.”

“This is because mana is pooled and the boss monster on the last floor can cause great damage if it goes out of control.”

“That is correct. Here is the prize.”

I threw candy at Mark. Mark received it.

“Ah….”

“I thought it was a great prize because it was a prize.”

On the other hand, Marc, who received the candy, looked at it for a while and was surprised.

“Huh? Isn’t this the ‘fruit of experience’?!”

“Eh?”

“That which doubles the training effect for half a day if eaten?”

“It’s a ridiculously rare item that can’t be eaten unless you’re a moderate duke!”

The students murmured. I pulled out a handful of individually wrapped candies from my pocket.

“There are many. Everyone should actively participate in the lecture.”

“Whoa, whoa….”

“The professor is good at magic, clears dungeons, and has a lot of money… ?”

“What a shame….”

I looked at Zion again.

“I will start with the conclusion. That dungeon is different from the dungeons that have appeared so far. Rather, not subjugating them is the way to prevent damage.”

“Yes? What do you mean?”

Shion made a face of disbelief.

“The advance party could not be found. Not subjugated not commonly found I’m calling this ‘multi-phase dungeon’.”

In the game, this is what is called an instance dungeon.

Since it was designed for repeated nogada, the contents are reset every time you enter it, and even if you subjugate it, only rewards come out.

“It’s a dungeon where every party you enter has the same structure, but you can’t meet each other because you’re sent to a place in a different dimension. It’s easy to be annihilated without prior information, and it’s tricky because cooperation is impossible.”

“Unlike the existing dungeons that accumulate mana, it is a dungeon that gradually consumes mana to maintain its status. Will someday perish naturally. Subjugation is impossible, but there is no risk of runaway. In other words, it is best to leave it alone.”

“Where in the world is such a dungeon?”

“There are many in Middle-earth. In the future, there will be more and more of them in the human world. Hmm. Well done. I should take this opportunity to present my thesis. Thank you for the great idea, student Zion.”

“Such a dungeon… But multi-phase really makes sense….”

Shion nodded her head in agreement. I lightly called attention.

“Then I will introduce the future curriculum. After three theoretical lectures, you will form a party and go into practice. Coincidentally, there are several low-level dungeons that are still being subjugated in the Academy Territory.”

“I will guarantee your safety during the lecture. But if you’re still worried, you should correct your class to another class right now. But I assure you, in my classes you will have an experience that you can’t have anywhere else in the academy.”

I looked back at the Earth Coffin students.

They are all full of will.

More than anything else, Luca, Tia, and Yuri are reassuringly supporting me.

That fact alone made me feel that this lecture would go well.

***

Three days later, Shion Ebels, who received a reply from his father, the guild leader, was surprised to see his contents.

“Wow, it was real.”

The reason Shion learned about the dangerous unknown dungeon was because his father was a powerful aristocrat and guild leader in the kingdom.

She wrote down the answers she heard in Wicker’s lecture and sent them to her father.

My father, the head of the guild, said that the situation was solved thanks to him, and praised the professor’s achievements in revealing the concept of the multiphase dungeon until the paper was torn.

In the process, it was only natural that Zion’s shoulders were strained.

“This lecture is great.”

I only want to listen to such a great lecture.

Wouldn’t it be better for the stupid kids who don’t recognize Professor Pedia’s true nature to drop it?

While Shion was rolling her hair for a moment, her friend, an aristocratic student, called her.

“Zion! Did you hear the news?”

“What news?”

“That dungeon studies professor! I already published my multiphase dungeon thesis!”

“Already?! How can a thesis come out in three days?!”

“I have a co-author. I heard it was Associate Professor Sersi Paniya. Who the hell is that?”
